Beetles first appeared on Earth at the same time as the earliest dinosaurs but turned out to be much better survivors, a new evolutionary study has shown. Today, there are an estimated 350,000 known species of beetle on Earth, and probably several million more yet to be discovered, say scientists. The insects account for about a quarter of all life forms on the planet. picked by AutumnLotus 11 months ago

What would it take to jam a planet's tectonics? It seems that a huge rise in atmospheric temperatures would do the trick, causing continents to grind to a halt, mountains to stop growing and earthquakes to cease. On Earth, the motion of magma in the mantle pushes continental plates around on the surface, but if the magma became too hot and runny it would lose the grip needed to do this. picked by AutumnLotus 7 months ago

A spectacular, rotating binary star system is a ticking time bomb, ready to throw out a searing beam of high-energy gamma rays – and Earth may be right in the line of fire. picked by AutumnLotus 9 months ago

Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. New work shows that if Earth had been slightly smaller and less massive, it would not have plate tectonics-the forces that move continents and build mountains. And without plate tectonics, life might never have gained a foothold on our wor... read full post picked by AutumnLotus 10 months ago

Google Earth has some amazing and interesting images to be found. Here are a few, shown in video form (if you can ignore the cheesy music). picked by tundramonkey 2 years ago

A mineral that acts like a sponge beneath Earth's surface stores more oxygen than expected, keeping our planet from becoming dry and inhospitable like Mars. The key to the abundant oxygen storage is the mineral majorite, which exists deep below Earth's surface in the mantle. Without the oxygen stockpile, Earth would probably be a barren planet hostile to life. picked by AutumnLotus 1 year ago

Some crucial ingredients for life on Earth may have formed in interstellar space, rather than on the planet's surface. A new computer model indicates clouds of adenine molecules, a basic component of DNA, can form and survive the harsh conditions of space, and possibly sprinkle onto planets as the stars they orbit travel through a galaxy. picked by AutumnLotus 1 year ago

In this essay, the father of the SMART-1 lunar mission, Bernard Foing of the European Space Agency, looks at the effect the Moon has had on the Earth, and explores how different our world would be if we had no planetary companion. Would life have evolved differently, or at all without our Luna? picked by DrNothing 1 year ago

This video explains that if we would dig a straight line between two points of the surface of the earth, and drop a capsule in it, it would take 42 minutes to reach the other side, no matter where. picked by Frog 3 months ago

Astronomers have spotted evidence of a second Earth being built around a distant star 424 light-years away. Using NASA's Spitzer Space Telescope, astronomers have spotted a huge belt of warm dust swirling around a young star called HD 113766 that is just slightly larger than our sun. picked by AutumnLotus 1 year ago

A team of water experts says the pattern of droughts and floods in South Africa shows our global warming was triggered by the variability of the sun’s irradiance rather than by human-emitted CO2. They say variations in South African rainfall patterns are keyed to periodic reversals of the sun’s magnetic field—and to the constantly changing distance between the sun and the earth a... read full post picked by AutumnLotus 1 year ago
